Subject: Off topic: Numactl "distance" wrong
Date: Fri, 3 Apr 2009 14:02:07 -0600	[thread overview]
Message-ID: <f3177b9e0904031302p8aef826u1874a8b9d9af0840@mail.gmail.com> (raw)

Sorry for an off topic, but I'm hoping somebody can point me in the
right direction of where to direct this question...

I have an Opteron system where I've seen the HW diagrams, and each of
4 sockets is directly connected (HT) to two other sockets, and two HT
hops away from a third (i.e. a simple square topology, no X in the
middle).

Yet, "numactl --hardware" shows but one hop to each socket:

# numactl --hardware
...
node   0   1   2   3
  0:  10  20  20  20
  1:  20  10  20  20
  2:  20  20  10  20
  3:  20  20  20  10

I know this is wrong.

Who would be the right person (or list) to talk about this?

I'm using the latest numactl 2.0.3-rc2 source and a 2.6.29.1 kernel.

Thanks,

Chris
